BACKGROUND OF THE INVENTION 1. Field of the Invention

This invention relates generally to point of sale systems and, in one particular embodiment, to a system, method, and computer program product for automatically analyzing a personal service session and completing a transaction therefor.

2. Technical Considerations

Purveyors of goods rely on point of sale (“POS”) systems to select merchandise from inventory and receive payments from consumers via cash, credit/debit cards, and/or various other payment instruments. Purveyors of services, such as salons, body art vendors, car washes, and other businesses where a personal service is performed for a customer, usually on-site, also rely on POS systems to receive payment for services that have been performed. However, for services, a merchant or merchant employee must generally cease performing services that provide a direct economic benefit to the merchant's business in order to catalog and manually enter the services that have been performed and the associated costs into the POS system. Accordingly, there is a need in the art for improved systems and methods which may reduce such potential sources of inefficiency.

SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention to provide a method, system, and computer program product for automatically analyzing a personal service session and completing a transaction therefor to overcome some or all of the deficiencies in the prior art.

For example, in non-limiting embodiments, a trigger event may include the identification of a word or phrase indicating that a particular type of service is beginning (e.g., a wake word, phrase, or command), a word or phrase indicating that a particular type of service is ending and another type of service is about to begin (e.g., a change of service word, phrase or command), a word or phrase indicating that a session has ended (e.g., a termination word, phrase or command), and/or the like. It will be appreciated by those skilled in the art that a trigger event may take various forms in accordance with the principles of the invention.

Non-limiting embodiments of the present invention are directed to an improved (POS) system for automatically analyzing a personal service session and completing a transaction therefor, in addition to associated systems, methods, and computer program products. In particular, non-limiting embodiments are directed to an improved POS system and method that utilizes one or more video cameras and/or other sensors to automatically generate an electronic invoice on a merchant device based on personal services performed for a customer. An artificial neural network, such as a convolutional neural network, may be used in some non-limiting embodiments to automatically match sequences of frames to types of services that have been provided during a personal service session. In non-limiting embodiments, the merchant device may be configured or programmed to generate a draft electronic invoice based on the automatically matched sequences of frames and allow the merchant to make corrections which are input back into the artificial neural network in order to improve the functionality of the merchant device and the algorithm in subsequent service sessions.

Referring now to FIG. 1, a system for analyzing a personal service session is shown according to a non-limiting embodiment. An automated POS system 1000 comprises a merchant device 10 in communication with a camera 12 and a peripheral device 20. In the non-limiting embodiment shown in FIG. 1, the camera 12 is integral to the merchant device 10. However, it will be appreciated by persons skilled in the art that various arrangements are possible and that, in non-limiting embodiments, a separate camera may be provided in communication with the merchant device.

In non-limiting embodiments, the peripheral device 20 may comprise one or more card readers, (NFC) receivers, RFID receivers, and/or other contactless transceivers or receivers, contact-based receivers, payment terminals, computers, servers, input devices, and/or other like devices that can be used to initiate a payment transaction. For example, the peripheral device 20 may include a further POS system such as an additional mobile POS system that is in communication with the merchant device 10. However, persons skilled in the art will appreciate that the use of one or more peripheral devices 20 is optional. For example, the merchant device 10 may include one or more card readers, (NFC) receivers, RFID receivers, and/or other contactless transceivers or receivers, contact-based receivers, input devices, sensors, and/or other like devices that are used to initiate a payment transaction. Moreover, such components may also be part of a separate computer or system and in communication with the merchant device 10. For example, in non-limiting embodiments, the merchant device 10 may comprise an internal receiver configured to accept payment from a customer device 10. Additionally or alternatively, the merchant device 10 may allow the merchant 16 and/or the customer 18 to view and/or verify an electronic invoice on an electronic display device located on the merchant device 10 and/or on another computer in communication with the merchant device 10. Moreover, the merchant device 10 may be programmed or configured to receive and record user input from the merchant regarding a transaction such as, for example, indicating that a payment has been received via cash or check.

With continued reference to FIG. 1, the video camera 12 is arranged to monitor a service location 14 where a merchant 16 may perform a personal service for a customer 18. Additionally, in non-limiting embodiments, one or more additional sensors such as cameras, microphones, heat sensors, motion sensors, weight sensors, capacitance sensors, other sensors, and/or the like (not shown in FIG. 1) may further be provided in communication with the merchant device 10. Data from such additional sensors may be processed by the system to detect start trigger events, end trigger events, service transition trigger events, and/or to classify frames and/or sequences of frames, and/or match such sequences to services that have been provided. It will be appreciated that various configurations are possible.

Referring now to FIGS. 2A-B, a flow diagram of a method for automatically analyzing a personal service session and completing a transaction therefor is shown according to a non-limiting embodiment. With reference to FIGS. 1 and 2A, in step 101, the video camera 12 monitors the service location 14. In step 103, while monitoring the service location 14, the merchant device 10 periodically or continuously processes video data from the video camera to detect a start trigger event indicating the beginning of a personal service session. Absent the detection of a start trigger event, the video camera 12 continues to monitor the service location 14 and process the video data to detect for a start trigger event.

In non-limiting embodiments, visual, audial, audiovisual, and/or other monitoring may be conducted periodically, continuously, or upon activation by the merchant. In further non-limiting embodiments, video camera 12 may collect but not store or communicate data until a start trigger event is detected, for example, by the video camera itself through an internally or externally performed image recognition process, such as the processes disclosed herein with reference to the automated POS system 1000. In further non-limiting examples, the video camera 12 may be configured to enter a “sleep” mode after a prolonged period of inactivity, during which no video data is collected, and may be further configured to respond to a start trigger event, such as but not limited to a wake word detected based on audio data received from a microphone, a signal from a weight sensor that a person has sat in a chair located in the service location, a signal from a motion sensor that one or more persons has entered the service area, and/or various other data from the video camera 12 or other sensor in communication with the automated POS system 1000. At such time the video camera 12 may resume collecting, communicating, storing, and/or analyzing video data of the service location 14. Persons skilled in the art will appreciate that various arrangements are possible in accordance with the principles of the present invention.

With continued reference to FIG. 2A, in step 105, upon detection of a start trigger, the merchant device determines that a personal service session has commenced and, in step 107, the merchant device begins collecting video output for analysis. In step 109, each frame of the video output (e.g., raw video data) or, in other non-limiting examples, each of a plurality of frames of the video output taken at regular or irregular intervals, is classified using an artificial neural network, such as a convolutional neural network (CNN). In step 111, sequences of frames are then classified in a post-processing step, which allows for the reduction of noise which may frequently occur when frames are classified individually. In step 113, each classified sequence of frames is compared to a database of potential service types, which may be generalized, may be identified in advance to correspond to the appropriate type of merchant, or, in some non-limiting examples, may be selected by a user, for example, by using an application in communication with the merchant device.

In the event that the classified sequence of frames is determined to not correspond to a potential service type, the system registers “none,” or no indication at all, for the relevant time interval and repeats steps 107-115 until a sequence of frames matches a potential service type or until an end trigger event or transition trigger event is detected. In response to a classified sequence of frames being matched to a potential service type, the system records that this service has been performed and optionally monitors a duration until a transition trigger event (e.g., 63 a in FIG. 4) is identified. Upon identification of a transition trigger event, the system repeats steps 107-115 until a sequence of frames matches a second potential service type or until an end trigger event or subsequent transition trigger event (e.g., 63 b in FIG. 4) is detected.

In non-limiting examples, if the system registers “none” for the entire period of time between two trigger events, the system indicates that an error has occurred, invites the merchant to make appropriate corrections, and records and/or transmits the corrections for future or concurrent use in improving the system, for example, via a machine learning algorithm associated with the CNN.

With continued reference to FIG. 2A, in step 121, once an end trigger event has been detected, a list of services that have been performed during the personal service session is generated and may be displayed electronically for the merchant to review, for example in the form of a draft electronic invoice on a display device located on the merchant device, a peripheral device, and/or other computer in communication with the system. In step 123, the system prompts the merchant to verify that the list of services is correct. With reference to FIG. 2B, in step 125, the merchant reviews the draft electronic invoice and provides an indication as to whether any corrections are necessary. If the merchant identifies inaccuracies, in step 126, the merchant is prompted to make any necessary correction manually. In step 127, data regarding the accuracy or inaccuracy of the most recent predictions is recorded and/or transmitted for future or concurrent use in improving the system.

In step 129, the list of services that have been provided is compared to a pricing database to match each service to its respective predetermined price. In non-limiting embodiments, the recorded duration of each type of service may also be accounted for in determining pricing. For example, the pricing database may include a price per unit of time for a particular service that is multiplied by the duration to determine a price. Additionally, in non-limiting embodiments, the pricing database may include information regarding combinations of services that may qualify a customer for a “package deal” or other discount. In non-limiting examples, in step 131, the system determines whether all or any subset of the services that have been provided during the personal service session qualify for a package discount, and, if so, in step 132, the discount is applied before the electronic invoice is generated in step 133.

With continued reference to FIG. 2B, in step 135, the system prompts the merchant to verify whether the electronic invoice, which now includes pricing information, is correct (e.g., that it is to be billed as-is). If the merchant determines that corrections or adjustments are required, in step 138 the merchant is prompted to make any necessary manual adjustments. In step 139, payment is requested from the customer.

In non-limiting examples, a payment request including the electronic invoice may be communicated to a customer device to request payment via an electronic wallet application, a mobile checkout process, and/or the like, and the system may automatically record that payment has been received in response to the customer completing a payment transaction. For example, the payment request may cause the customer device to display one or more graphical user interfaces (GUIs) for completing a purchase with credentials, inputted account data, and/or the like. In further examples, a payment request may be displayed on a display device that is accessible to the customer for verification, and payment may be requested via cash or portable financial device. Persons skilled in the art will appreciate that various arrangements are possible in accordance with the principles of the invention.

Referring now to FIG. 3, a process for classifying each of a plurality of frames 50 a-e using a CNN is illustrated in greater detail according to a non-limiting embodiment. In particular, the non-limiting illustration shown in FIG. 3 follows one frame 50 c of a plurality of frames 50 a-e through a classification process.

As illustrated in FIG. 3, a frame 50 c is divided into a plurality of sub-frames (e.g., 52). Each sub-frame is then processed according to a plurality of filters to generate a plurality of filtered sub-frames (e.g., 52′-52″″). Each sub-frame is then divided into a plurality of sub-sub-frames (e.g., 54) and each sub-sub-frame is processed according to a plurality of further filters to generate a plurality of filtered sub-sub-frames (e.g., 54′-54″″). In non-limiting embodiments, the plurality of further filters applied to the sub-sub-frames may correspond to the plurality of filters applied to the sub-frames such that the filters may be used to more specifically identify where in each sub-frame various relevant features occur. It will be appreciated that the sub-sub-frames may be further divided into a plurality of further sub-sub-frames (not shown in FIG. 3) and also processed according to a plurality of filters, and that such further division and processing of those sub-sub-frames may also be performed. Based on the features that are identified in each filtered sub-sub-frame, the system may identify a fully-connected hidden layer which is used to predict what event or events 60 are observed based on the frame 50 c. The combination of events 60 which are predicted to have occurred are then used to generate an overall predicted activity and to produce a classified frame 62 c which is associated therewith.

Referring now to FIG. 4, a process for classifying a plurality of frames 50 a-l is shown in greater detail according to a non-limiting embodiment. As illustrated in FIG. 4, upon the identification of a start trigger event 80, the automated POS system determines that a personal service session has begun and begins collecting video output for analysis. A plurality of sequential frames 50 a-l are classified as discussed above with reference to FIG. 3 to generate corresponding classified frames 62 a-l.

In non-limiting embodiments, one or more transition trigger events (e.g., 63 a, b) may be utilized to aid the automated POS system in determining when one service ends and the next service begins and to thereby group the classified frames 62 a-l. For example, in the non-limiting illustration shown, classified frames 62 a-e which occur between the start trigger event 80 and first transition trigger event 63 a are identified as corresponding to a first service period 64 a, classified frames 62 f-i which occur between first transition trigger event 63 a and second transition trigger event 63 b are identified as corresponding to a second service period 64 b, and classified frames 62 j-l which occur between second transition trigger event 63 b and end trigger event 82 are identified as corresponding to a third service period 64 c.

By grouping the classified frames in this manner, the system can efficiently predict what type of service has been provided during each service period by cross-referencing the observed activities which occur most frequently among the classified frames (e.g., 62 f-i) during the relevant service period (e.g., 64 b) with a database of services which the merchant typically provides (or plans to provide with some measure of frequency) and utilize this data to generate a classified sequence of frames (e.g., 65 b). Upon identification of an end trigger event 82, the automated POS system determines that the personal service session has ended and aggregates the classified sequences of frames 65 a-c to generate a list of types of service 66 (and, in some non-limiting examples, the durations thereof) which have been provided during the personal service session, which forms the basis of an electronic invoice.
